When someone dies for another, it means that they have judged the person for whom they died as worthy of the sacrifice. But what makes the sacrifice of Jesus so remarkable was that we are so unworthy.
Scarcely would we die for a good person, but Jesus died for bad people. We who were sinners, were undeserving. But God who is love demonstrated his love towards us because he is love, not because we were worthy of love.
Isn’t it wonderful knowing God loves us even though we didn’t deserve it!?
